I’ve just signed up to pro and have been trying to enable speed optimisations. I understand we need to enable proxy (orange cloud) for these affects to work. However after enabling proxies the website fails to load generating the above error.
I’ve fixed this by switching the proxies off but I dont think any of the optimisations are now active as my site speed including server response time is still terrible.
Welcome to Cloudflare!
Check out the community tip for these issues, it has some quick fix suggestions:
Most commonly, it’s because your SSL/TLS Mode is set to Flexible when it should be Full (Strict), causing Cloudflare to send HTTP requests to your origin, your origin responding with a redirect to HTTPS, and an endless loop!
You can change your SSL/TLS Mode within the Cloudflare’s dashboard, inside of your website’s settings, under SSL/TLS → Overview, or via this magic link: https://dash.cloudflare.com/?to=/:account/:zone/ssl-tls
There’s a troubleshooting document here as well: ERR_TOO_MANY_REDIRECTS · Cloudflare SSL/TLS docs
